Why make Radio locked in BTF version 6.0

[Neo]

Hi, Mike
  I have noticed that you added lock and unLock functions in bluetooth Framework 6.0. It would be impossible that if I make two inquiry thread at the same time. If I want to inquiry the remote device's services and at the same time send a file to another remote device, these was allowed in bluetooth specifications. But what's happened in BTF6? The two procedures would be implement one by one,  rigtht?
So I thank it lowers the efficiency of the buletooth dongle.

Good day!

Lock and Unlock functions are for internal usage only.

Some drivers do not allow make discovering and connecting (even connecting not sending) operations at the same time. To synchronize that there was added lock and unlock functions (the same functions was added for IrDA).

The sending operations are executing in parallel with discovering.

Thank you, I understand now.

By the way, when will you plan to release BTF6.0
